PointCloudExtractor

Serializes the geometry of the feature into the Blob Attribute based on the selected writer format.

Parameters

ClosedFormat

The point cloud format used to encode the blob.

ClosedFormat Name Attribute

An attribute to preserve the specified format value for future use.

ClosedBlob Attribute

The attribute that will contain the resulting blob.

Note that when writing the Blob Attribute, you may need to adjust the attribute type to an unbounded data type to avoid truncation of the blob.

Usage Notes

  • The PointCloudReplacer may be used to do the reverse operation and convert the encoded blob back to the original data.
  • Alternatively if the point cloud is not required as a geometry on the feature for future processing, the AttributeFileWriter transformer can be used to dump the Blob Attribute directly to a file.
  • To carry out a similar operation on vector data, please use the GeometryExtractor transformer. For raster data, please use the RasterExtractor.
  • Currently supported formats include:
    • ASPRS Lidar Data Exchange Format (LAS)
    • ASPRS Lidar Data Exchange Format Compressed (LAZ)
    • Cesium 3D Point Cloud (pnts)

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
